GAS BURNER.

Application iled January 4, 1921.

O all w hom t may concern Beit known that I, NELSON T. Wninnociz. of Framingham, in the County of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Gras Burners, of which the following is a specification.

My invention relates to a. new and useful improvement in gas burners for heating purposes, which is simple to make and provides opportunity for the thorough mixing of the gas and air and is an improvement upon any burner of this type of which I am aware, my burner enabling the gas and air to be thoroughly mixed before being` delivered to the burner proper in a chamber which may be adjustable in size.

My invention will be understood by reiterence to the drawings, in which it is shown embodied in its preferred form.

Figure l is a plan view;

Fig. 2 a longitudinal section through Fig. l;

Fig. 3 an end view showing the gas inlet, and

Fig. d a modification, in longitudinal section;

Fig. 5 being a plan view thereof.

A is a burner support which may be cast or otherwise constructed. It comprises a hollow shanlr A1 open at one end, the other end of which is enlarged as at fr?, and closed in to form a supply chamber a2 into which leads a mixing passage al. Into the opening a in one wall of the supply chamber n2 is preferably driven or otherwise fixed a burner B the top of which, preferably flat, is preferably provided with a series of openings b for gas jets extending into the chainber a2. The burner is provided about its periphery with a lip b1 which overhangs a concave annular recess 52 located just beneath it. having a series of perforations 713 for jets which extend outwardly at an angle of approximately 45 degrees with the openings I) so that the gas jets passing out through the openings b3 will be guided more or less by the lip h1 and their flames will be separated from the flames of the gas jets passing out through the openings Z). It will be seen therefore that the lip h1 performs an important function in that it ensures a number of separate flames corresponding with the number of perforations in` the burner.

Into the hollow shank A1 slides a tube C Specification of Letters Patent.

closed at one end except for a central per foration in which the gas pipe l) is fixed. About the closed end of the tube C are also a number of perforations i to serve as air intakes, which are preferably arranged es shown (see Fig. 3) that is, at substantially a tangent to the inlet tube C, so that as the gas comes in through the pipe l) and draws in air through the openings Z the air given a spiral or swirling movement so that it readily and thoroughly mixes with the gas, thus forming a good mixture for com-- bustion, more perfect than the mixture in any burner of which I am aware. The inner' tube thus forms a mixing chamber and as the inner tube C may be moved longitudinally in the shank A1, the mixing cham bei' may be adjusted in size so that the time of this mixing process may be lengthened or shortened as required by the character of the gas used and a mixture secured of the thproughness desired. Moreover my structure allows the adjustment of the distance between the standpipes and the desired position in the stove.

This form of burner it will be seen is very simple and, as the principal part of it may be made by casting, it is very inexpensive. The openings b2 in the burner itself may be arranged in any convenient way below the lip b1 so that this lip may serve to separate the iiames coming from the sides of the burner from those in the top of the burner. The openings b and b3 are preferably staggared with relation to each other, and are thus between each other in a vertical plane.y as will be readily understood from Figs. l and 2, so that the flames or jets issuing from said openings will be separated from each other, as hereinbefore stated.

Instead of having perforations in the top of the burner or in addition thereto a second concave annular recess 67 may be made below the first recess 722 and a second peripheral set of openings b4 provided for gas jets, a second lip Zi being provided to separate the jets from h2 from the gas jets from 794, and either set of jets may be at an angle as in Figs. 4 and 5.

What I claim as my invention is 1. A gas burning device comprising a hollow body having a tubular extension projecting from one side thereof, a perforated burner proper fitted to said hollow body, a pipe fitted in said tubular extension and having a partially closed outer end provided with an annular serie-s of inelined and tangentially arranged air-inlet openings, and e gas inlet pipe surrounded by said openings which cause the entering air to have a swirling movement es it enters the niixingchainber afforded by said first-named pipe.

2. A gas burning device comprising :1,

hollow body having a tubular extension 1nrojeotingfrom one Side thereof,y a burner proper fitted into the upper side o'll sai d body and having at its outer part two serie@4 ol? perrore-#tions7 the pei-tort` ions et one Series bein( disposed in staggered relation to the perforations oi'rE the other Series a pipe adjustably litting` said tubular eXtenSion and having` a partially closed outer end, and means for admitting air and gas into said pipe whieh afforde an air and gee mixing chamber communicating' with the chamber of said hollow body.

3. A gas burning device comprising a hollow body having a tubular extension projeoting from one' side thereof, a burner proper itted into the upper side of said body and having at its outer part two series of perforations, the perforatioue ot one Series being disposed in :staggered relation to the perforations or the other series, a pipe adjustably fitting said tubular extension and having a partially closed outer end having` an annular series of tangentially arranged inlet perforations and a gas inlet pipe iitted fr@ ifioeic into the end of said iirst-narned pipe which aords an an: and gas mixing ehainber Cornhollow body having a tubular extension projeeting from one Side thereof, a. burner proper itted into the upper Side of said hollow body-and 'having a circula-r Ceries or perforations in its top7 near its periphery. and a second series or perforations just below its `top and arranged in staggered relation to said iirst-nained pertorations so that the peri'orations of said second series come between the said first-named perfor; tions in a vertical planey' said burner proper having also an annular' lip at its periphery above Said second series of perforations which are inclined at an angl-e orf approximately forty-five degrees to Said rst-nanied perforations, a pipe adpistably mounted .n

said tubular extension and having` a partially closed outer end with an annular Series 0i inclined air inlet perforations at the periphery or' its end,a gas inlet pipe fitted into the end of said first-named pipe which aords an air and mixing chainber communicating with the chamber of said hollow body on which said burner proper is mounted.
